My little sister who is 16 just started getting into film and dark room photography. Shes taking a class in high school and is hooked. My mom is getting her an enlarger and a film camera for Christmas, and I was thinking of getting her some film or paper, however I think it would be more useful to give her a gift certificate to get hat she knows she needs. Where would be a good place to get a gift certificate for dark room camera supplies...? THANKS!!
